so , 2018.9.05 has a different answer, C, DHCP issue. Which one is correct? I don't think the question any differently.
- x: P) R4 M' }+ y$ @+ u8 L' O0 H- ]8 n! v U" g. i# m0 Y
3 y6 I5 J# K% a. s, e" C) V
R5 configuration :-6 q. k1 N* U: W# f
int gig0/07 e8 G5 ?( w9 U, T n6 {
ip address dhcp- V" h1 f* J3 V
This interface not getting dhcp ip address from R4. So even though OSPF configuration was like 0.0.0.0
8 x' s5 r2 [0 o; ^( s3 w0.0.0.0 area 0 , because this interface does not get correct ip address from DHCP it can’t participate in
* J F) D& Y- v# eOSPF.4 [/ x; C! T; G; H9 u% ~0 c
R4 configuration :-

ip address dhcp .
% Y# J! R1 u: @This interface on R4 should have ip address configured on it instead of ” ip address dhcp ” . Hence its not

& V9 K2 [) A- l2 J+ R8 zR4 also had ospf configured as network 0.0.0.0 0.0.0.0 area 0. So all interface can participate if they are7 U1 D( v6 f. k& r7 P$ k
up and if they have ip address.) H# A" J- Q R- Q3 J( ?
But because R5 interface connected to R4 could not obtail correct dhcp ip address from R4 due to DHCP
/ C3 [6 r: T2 J4 \issue they wont form ospf neighborship.
+ ~, ]$ ]$ ^/ M8 }So correct answer is DHCP issue between R5 & R4. |
